I see one of the immediate effects of the C-19 outbreak is a sudden and statistically significant drop in emissions and pollutants due to the fall off in economic and social activity globally.
Somewhere between 25% and 50% lower emissions being observed in places like New York, or so I understand from early news reports. NORA is a devious AI. Winnowing the parasite as well as attacking the activity which is unbalancing the system.
Saw an article covering comments by the UN Environmental Agency chief which touches on the communications between our environment and ourselves, and does see the virus risk being linked to other existential risks to humanity.
